Does your CX9 use the SD or DVD version of Whereis? Mazda use both depending on model, the majority use SD i think, but Mazda 6 & CX9 from 2008 onwards do use dvd. If yours uses the DVD, both C1 and C2 V18 are available here: [Only registered and activated users can see links. ]. If it uses the C1 dvd, V19 is now available: [Only registered and activated users can see links. ]. I haven't been able to establish if the dvd mazda units use C1 or C2 sorry, you may have to experiment.
I don't think any SD copying solution is available on the net unfortunately.
